Subject: [PATCH v1 1/1] arm64: tegra194: p2888: Correct interrupt trigger type of temperature sensor
Date: Mon, 12 Jul 2021 02:49:39 +0300 [thread overview]
Message-ID: <20210711234939.28103-2-digetx@gmail.com> (raw)
In-Reply-To: <20210711234939.28103-1-digetx@gmail.com>
The LM90 temperature sensor should use edge-triggered interrupt because
LM90 hardware doesn't deassert interrupt line until temperature is back
to normal state, which results in interrupt storm. Correct the interrupt
trigger type.
